Letters Patent No. 111,760, dated February 14, 1871.

IMPROVEMENT lN MILL-STONE FEEDERSYAND GR-AlN- SCOURERS.

The Schedule referred to in these Letters Patent: and making part of the same.

face of the cylinder within which the scourers of a feeder and cleaner revolve, and in so attaching the scourers upon their shaft that they can be readily removed, and in the form of the scourers.

In the drawing- The scourers and the cylinder in which they revolve are shown, but the other parts of the machine are not shown, being constructed in the usual manner, and substantially as shown and described in .a patent granted to me and dated April 7, 1868. p The-scourers are driven, as shown in said patent, or in any other suitable well-known manner, and the driving devices are not shown in this application.

In the drawing-- A represents a cylinder, within which the scourers Y B revolve.

The cylinder is corrugated on the inside, as shown in fig. 2, and it stands on a board or platform, G, as

usual..-

D represents parts of the frame, which is construct ed and arranged as usual.

E is a shalt upon which the scourers B are placed, being separated from each'other by the washers c, and held upon the shaft by the nut b.

.A greater or lesser number of scourers can be used, by decreasing or increasing the thickness of the washmovable and adjustable, as described, so that they may be adapted, both in kind and number, ,to thework to be performed. l

The form of the scourers which I now use is shown in Figure 3; those which I formerly usedwere-complete disks.

These have a portion of the metal cut away at c c, as shown,'aud, when placed on the shaft, I arrange them so that the open places 0 c in one scourer are over the'wings (Z (Z of that immediately above or below;

The advantage resulting from this form is that the grain can fall to the center, and then be thrown out from the center by the centrifugal force of each alternate scour-er. In other respects thescourers are constructed as usual. v p

The corrugated cylinder has this advantage over one having a smooth interior: There must be alittle space between the edges of the scourers and the surface of the cylinder, and when the cylinder is corru gated, as shown and described,'the grain in this space.

is more likely to be kept in motion and brought again 'to the scourers than when the surface is-smootl'r. 1

now make the cylinder of glass.

This material has important advantages over any other now in use for this purpose, the chief of which is its durability.

The constant friction of the grain upon metal cylinders in use rapidly wears them away; butthe glass is so exceedingly hard that such friction will' have no perceptible effect for a long time.

It the glass be transparent the operatorcan see when the cylinder is empty fromany position and without approaching the device.

It is about eight inches long, anl in diameter about the same. i

H is the hopper. p

The lower end of the shaft may be supported in any suitable bearing, located where convenient, and the upper end may, extend above the frame to receive a driving-pulley.

\Vhat I claim as new is as follows:

1. The corrugated cylinder A, when made of glass, in combination with the scourers B and shaft E, substantially as and for the purpose set forth.

, 2. The combiuatiim of the scourers B, shaft E, washers a, and nut b, substantially as specified.

3. The segmental scourers B, constructed and arranged upon the shaft E, substantially as and for the purpose set forth. v I
